There's a giant misconception in "people die from marathoning", people don'tdie from the marathon, but already have a cardiovascular abnormality, enter the marathon, and the stress from the marathon magnifies the abnormality which gives into to the stress and causes the death.

In the case of crossfit, rhabdomyolysis isn't a predeveloped condition like you see in the cardiovascular abnormality deaths in marathons. Rhabdomyolysis is 100% induced through a crossfit workout prescription. Its not caused by a genetic or physical abnormality, its completely caused by massive overwhelming muscle trauma

Cardiovascular diseases responsible for sudden unexpected death in highly conditioned athletes are largely related to the age of the patient. In most young competitive athletes (<35 years of age) sudden death is due to congenital cardiovascular disease. Hypertrophic cardiomyopathy appears to be the most common cause of such deaths, accounting for about half of the sudden deaths in young athletes. Other cardiovascular abnormalities that appear to be less frequent but important causes of sudden death in young athletes include congenital coronary artery anomalies, ruptured aorta (due to cystic medial necrosis), idiopathic left ventricular hypertrophy and coronary artery atherosclerosis. Diseases that appear to be very uncommon causes of sudden death include myocarditis, mitral valve prolapse, aortic valve stenosis and sarcoidosis. Cardiovascular disease in young athletes is usually unsuspected during life, and most athletes who die suddenly have experienced no cardiac symptoms. In only about 25% of those competitive athletes who die suddenly is underlying cardiovascular disease detected or suspected before participation and rarely is the correct clinical diagnosis made. In contrast, in older athletes (≥35 years of age) sudden death is usually due to coronary artery disease, and rarely results from congenital heart disease.

Rhabdomyolysis is also a "race against death" condition; if medical treatment is completely ignored or delayed for a long time, the person is going to die.

This isn't going to happen with an acl mcl tear, meniscus tear, fracture, condromalacia, tendonitis, torn muscle ligament tendon found in sports, where if ignored, yes it will be painful, but its not going to immediately kill the person.

If the crossfitters that rhabdo-ed did not have immediate access to an emergency room, there would be a rhabdo death count of 132

The injuries are non comparable

Other sports and competitions are not putting people in an injury state that is a race against death- but crossfit is.

1 of every 20 Crossfit rhabdo-er will have permanent kidney scarring and will need a kidney transplant later on.
1 of every 100 Crossfit rhabdo-er will die.

The CrossFit program is designed for universal scalability making it the perfect application for any committed individual regardless of experience. We’ve used our same routines for elderly individuals with heart disease and cage fighters one month out from televised bouts. We scale load and intensity; we don’t change programs.

The needs of Olympic athletes and our grandparents differ by degree not kind. Our terrorist hunters, skiers, mountain bike riders and housewives have found their best fitness from the same regimen. . .
